Iron-Catalyzed ortho-Selective C-H Borylation of 2-Phenylpyridines and Their Analogs

Treatment of 2-phenylpyridines (or their analogs) with a 9-bicycloboranonane dimer (9-BBN dimer) in the presence of a catalytic amount of a commercially available iron salt, FeBr3, gave ortho-borylated products in moderate to excellent yields with good functional group tolerance. The reaction proceeded in good yield, even in gram-scale, and also occurred at the C-H bond of heteroaromatic compounds. The cost of the C-H borylation is dramatically lower than that of a previously reported similar palladium-catalyzed reaction. The products exhibit an intramolecular B-N Lewis acid-base interaction and fluoresce in both solution and solid states due to their electron push-pull structures.

Silver-Catalyzed Minisci Reactions Using Selectfluor as a Mild Oxidant

A new method for silver-catalyzed Minisci reactions using Selectfluor as a mild oxidant is reported. Heteroarenes and quinones both participate in radical C-H alkylation and arylation from a variety of carboxylic and boronic acid radical precursors. Several oxidatively sensitive and highly reactive radical species are successful, providing structures that are challenging to access by other means.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, Application In Synthesis of 5-Bromo-2-phenylpyridine, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 27012-25-5

A Convenient Approach To Synthesize o-Carborane-Functionalized Phosphorescent Iridium(III) Complexes for Endocellular Hypoxia Imaging

The structure?property relationship of carborane-modified iridium(III) complexes was investigated. Firstly, an efficient approach for the synthesis of o-carborane-containing pyridine ligands a?f in high yields was developed by utilizing stable and cheap B10H10(Et4N)2as the starting material. By using these ligands, iridium(III) complexes I?VII were efficiently prepared. In combination with DFT calculations, the photophysical and electrochemical properties of these complexes were studied. The hydrophilic nido-o-carborane-based iridium(III) complex VII showed the highest phosphorescence efficiency (abs.?P=0.48) among known water-soluble homoleptic cyclometalated iridium(III) complexes and long emission lifetime (tau=1.24 mus) in aqueous solution. Both of them are sensitive to O2, and thus endocellular hypoxia imaging of complex VII was realized by time-resolved luminescence imaging (TRLI). This is the first example of applying TRLI in endocellular oxygen detection with a water-soluble nido-carborane functionalized iridium(III) complex.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Electric Literature of 27012-25-5, you can also check out more blogs about27012-25-5

Platinum(ii) polymetallayne-based phosphorescent polymers with enhanced triplet energy-transfer: Synthesis, photophysical, electrochemistry, and electrophosphorescent investigation

Two series of new phosphorescent copolymers with bicarbazole-based platinum(ii) polymetallayne backbones have been successfully prepared through Sonogashira cross-coupling with different IrIII ppy-type (ppy = 2-phenylpyridine anion) complexes as phosphorescent centers. The photophysical investigations not only indicate a highly efficient triplet energy-transfer process from the polymetallayne segments to the phosphorescent units in the polymer solution, but also figure out the structure-property relationship between the triplet energy-transfer process and the energy-levels of different excited states. In addition, the phosphorescent copolymers can produce yellow-emitting phosphorescent OLEDs (PHOLEDs) with high EL efficiencies and a current efficiency (etaL) of 11.49 cd A-1, an external quantum efficiency (etaext) of 4.38%, a power efficiency (etaP) of 3.78 lm W-1, and red-emitting PHOLEDs with a etaL of 5.86 cd A-1, etaext of 10.1%, and a etaP of 2.29 lm W-1, representing very decent electroluminescent performances achieved by the phosphorescent copolymers. Herein, this work not only furnishes very important clues for further polishing of this category novel phosphorescent polymer, but also provides a new approach to the design and synthesis of highly efficient phosphorescent copolymers.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
